d. Loop your index fingers through the finger holes of the latching mechanisms on either side of
the NSM module.
Note: If you are inserting the bottom NSM module, and if the bottom rail is obstructing access
to the latching mechanisms, place your index fingers through the finger holes from the inside
(by crossing your arms).
e. With your thumbs, press down and hold the orange tabs on top of the latching mechanisms.
f. Gently push forward to get the latches over the stop.
g. Release your thumbs from the tops of the latching mechanisms, and then continue pushing
until the latching mechanisms snap into place.The NSM module should be fully inserted into
the shelf and flush with the edges of the shelf.
Step 9. Reconnect the cabling to the NSM module:
a. Reconnect the storage cabling to the same two NSM module ports.Cables are inserted with
the connector pull-tab facing up. When a cable is inserted correctly, it clicks into place.
b. Reconnect the power cord to the power supply, and then secure the power cord with the
power cord retainer. When functioning correctly, a power supply's bicolored LED illuminates
green.
Additionally, both NSM module port LNK (green) LEDs illuminate. If a LNK LED does not
illuminate, reseat the cable.
Step 10. Verify that the attention (amber) LEDs on the NSM module containing the failed DIMM and the shelf
operator display panel are no longer illuminated.
When the automatic checks are completed on the replacement DIMM, the attention LEDs turn off.
Step 11. Verify that the NSM module is cabled correctly.
You can download and run ThinkSystem Intelligent Monitoring Config Advisor to verify cabling. If
any cabling errors are generated, follow the corrective actions provided.
